ELE CTRIG-LIGHT-B UTTON-TURNING DEVICE Specification of Letters Patent.

Patented June 1.5, 1909.

Application filed August 8, 1908. Serial No. 447,505.

To all whom it may concern:

Be it known that I, ABRAHAMR. HURsT, a citizen of the U ited States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Electric- Light-Button-Turning Devices, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to a device for turning the buttons of overhead or elevated incandescent electric lights, and the object of my invention is to provide simple means which can be readily attached to the lamp socket and button, and which device is opcrated by means of a depending chain, or the like.

T o the above purposes, my invention consists in certain novel features of construction and arrangement of parts, which will be hereinafter more fully set forth, pointed out in the claims, and illustrated in the accompanying drawings, in which:

Figure 1 is an elevation of a device of my improved construction applied to the socket of an ordinary incandescent electric light, the light fixture being shown in dotted lines; Fig. 2 is an enlarged cross section taken on the line 22 of Fig. 1 5 and Fig. 3 is a section taken on the line 33 of Fig. 2.

Referring by numerals to the accompanying drawings: 1 and 2 designate the mating halves of a ring which is clamped around. an electric light socket, and the ends of said main parts are hinged together on one side, as designated by 3, and the opposite ends are normally held to one another by means of a screw 4', or like fastening device.

Formed in the center of the part 1 is an opening 5, through which the rotary stem of the switch within the socket projects, and which stem is provided with the usual button 6.

Fixed to the member 1 to one side of the opening 5 therein is an outwardly projecting arm 7, and formed integral with the outer end of said arm is a ring 8, which occupies a vertical position immediately in front of the opening 5. Arranged for rotation against the rear face of this ring 8 is a ratchet wheel 9, in the center of which is formed a slot 10, which receives the button 6 when the device is applied to the electric light socket, and

/ formed on or fixed to the outer face of the ratchet wheel 9 is a series of hooks or retaining clips 11, which engage against the outer face of the ring 8, and thus maintain the ratchet wheel 9 in proper position on said ring 8.

Arranged against the rear face of the ratchet wheel 9 is a ring 12, and fixed to the inner face of the ratchet wheel 9 are hooks 13, which engage through said ring 12 and against the outer face thereof to hold the same in position to rotate on the inner face of the ratchet wheel.

Formed integral with the ring 12 is an arm 14, and pivotally mounted thereon is a pawl 15, the point of which engages between the teeth of the ratchet wheel 9, and bearing on top of this pawl 15 is a spring 16, which is fixed to the arm 14.

Carried by the arm 7 is a coil spring 17, one end of which is extended, as designated by 18, and connecting the upper end of said extension with the upper portion of the arm 14 is a link 19. Formed on or fixed to the arm 7 is a finger 20, which forms a stop to limit the movement of the arm 14 in one direction.

Attached to the extreme upper end of the arm 14 is one end of a chain or cord 21, the lower end of which is provided with a ring 22.

When my improved device is in position foruse, the matinghalves 1 and 2 are clamped upon the electric light socket, with the button 6 of the switch projecting through the slot 10 in the ratchet wheel 9.

When the chain or cord 21 is engaged and pulled downward, the arm 14 is likewise moved downward, and the ring 12 integral with the lower end of said arm is partially rotated, and as the point of the pawl 15 engages against one of the teeth of the ratchet wheel 9, said ratchet wheel is likewise artially rotated, and this partial rotation gives the button 6 a quarter turn, thus turning the switch within the socket on or off, as the case may be.

The downward movement of the arm 14 necessarily moves the spring 17 so as to store power therein, and which power is exerted when the pawl on the chain 21 is released, and thus the arm 14 is rotated to its normal position against the finger 20, during which movement the point of the pawl 15 rides over the teeth of the ratchet wheel 9, which ratchet wheel is held against reverse movcment by its engagement with the button 6.

A device of my improved construction is simple, inexpensive, easily applied to the sockets of incandescent electric lights, and l provides simple means whereby the buttons 1 of elevated electric lamps can be conveniently 2 turned.

I claim:

1. A device of the class described, comprising atwo-part ring adapted tobe clamped on the socket of an incandescent electric lamp, an arm carried by said ring, a bearing ring fixed tosaid: arm, a ratchet wheel arranged for rotation upon the bearing ring, which ratchet wheel is provided with a slot which receives the button of thelamp switch, a spring-held arm journaled upon the bearing ring immediately adjacent the ratchet wheel, and a spring held pawl carried by said spring-held arm, the point of which pawl engages the teeth of the ratchet wheel A 2. A device of the class described, comprising atwo-part ring adapted to be clamped on the socket of an incandescent electric lamp, an armrigidly fixed to one ofthe parts of the ring, a bearing ring integral with said arm, hooks formed. on said bearing ring, a ring arranged for rotation on said hooks, an arm integral with said last mentioned ring, a ratchet wheel arranged for rotation be tween the ring carrying the hooks and the ring carrying the arm, a spring held pawl carried. by the second-mentioned arm, the point of which pawl engages the teeth of the ratchet wheel, and a stop fixed on the first mentioned arm for limiting the rearward movement of the second mentioned arm.

In testimony whereof, I have signed my name to this specification, in preseme of two subscribing witnesses.
